Bests & Worsts Reviews from Amazon

I bought this set, and at the beginning I love it. after 9 months the set lost its golden bath. I took it to the jeweller and he tried to give it a golden bath, it was not possible. I asked him to silver plated then, and it was also not possible. He told me that the problem was the the set was not made of copper, as it is disclaimed by the seller, but of iron. I wrote to the seller asking him to tell me how was he able to give it the golden color, in order for me to tell my jeweller. So far I haven't received and answer. The set is not inexpensive to be without color after 9 months only.
